TO ALL 'IO .WHOM IT MAY CONCERN:

Be it known that I, JOSHUA KIDD, gas origineel', of Great Newport street, London, in the county of Middlesex, in that part of Great Britain and Ireland called England, have 'invented a new and improved Apparatus for arburetting Gras; and I hereby declare that the following is a full, clear, and exact description of the construction and operation of the same,A reference being had tothe drawings hereunto annexed, making' partof this specification'. u v

My improvements consist in the application of a novel form ofgas-tight vessel, called a carburettor, for

holding heavy non-volatile liquid hydrocarbons, made round, square, 'or other convenient shape, with a tubular or conical-shaped chimney ornperture through its centre; and in a novel mode of supplying the Carburettor.

with` the liquid hydrocarbons which are vaporia'ed by the heat Of the gas ame. I-Iithert this method of car; buretting gas, with the heated vapor of heavy liquid hydrocarbons, ha's'been performed with a circular vessel. or boiler made with a iight. toburn underneath it, and supplied with Oil at intervals as required. I Experience has shown that when a Carburettor thus formed has been fin use 'for a short time it gives off very little vapor to the gas on account ofthe deposit of tarry matter at the bottom of the vessel, which obstructs the heat. The lighter portion of the oil is also driven'off first, so that the light is continually varying .in intensity. Those defects, added to the trouble oi' -regulating the heat and replenishing the oil vessel, has caused the process-in many cases to be abandoned This invention is intended to remedy those defects by heating the liquid from the top instead of from the bottom of its vertical column, also byuan'improved mode of regulating the heat and supplying the liquid to the Carburettor, which will be better understoody by reference to the drawings annexed, making part of this specification. i

Description cf Drawings.

Figure 1 shows a section of the carburetting vessel F, suitable for carburettingthe gas for a public street lamp.

'A is the-inlet and B the outlet pipe. C shows the chimney or heating aperture formed through the apparatus, which may be made circular, conical, oblong or other convenient shape. This chimney -is supplied at the topwith a cap or hot-air interceptor, D, for regulating the heat; this cap is attached tO a wire spindle, E, which turns in a tub'c or'journal attached to the Carburettor. By turning this wire the cap, more 'or less, closes the top of the chimney, and' thus increases the heating power of the Haine Or diminishes it. The carburetting vessel iF. may be made ornamental, and any desired shape orsizc, to suit different tastes or requirements; and instead of one jet of gas, anyrequired convenient number of jetsmay'be used. The apparatusinay thus be adapted for sun or ceiling lights, or other purposes where a large body of lightiisjrequired. A section of an apparatus, suitable for a sun or ceiling light, is shown at Figure 5. The heat interceptor D, in this arrangement, may be made to slide pp and down upon the outlet pipe B, by any bell-hanging arrangements of wire, as shown at D. 'I supply theearburettor F with oil by means of an intermittent fountain feeder. A section of two methods of forming this intermittent feedervis shown at Figures 3 and 4; both those feeders are governed by the mechanical laws of atmospheric pressure'. Fig. 4 is used to feed the Carburettor when it is required to supply-it with-.oil from a position higher than' the carburetting vessel. G is a pipe for the passageof gas, and H a pipe for supplying the oil. Those two pipes* shown at iig. 4 are connected, from any distant position, to the two pipes represented by similar letters at iig-1, whenfthenoil falls below the terminationfof the two pipes G and H in the Carburettor. Gas'rises. throng-h pipe G into the aforesaid vessel K, in iig. 4, and a proportionate amount of Oil falls into the Carburettor through the pipe H, till-the termination ofthe said pipes G and H is a-gain sealed by the oil. "l shows-a hydraulic screw-.plug for charging vessel K with oil, during which operation the stop-cock Rjsbeuld be closed. i u

Figure 3 shows a modification of `tig. 4. .It is preferable to use this description of feeder for street-lamp earburettors, or when it is desire-d to placethe intermittent feeder upon the same level as the carburetzing vessel. G is a tube for the supply oi' air to vessel K. Air enters, when the oil falls below the Outlet of this vessel, in theregulating chamber M.v The pipe II conducts the oil and is attached tothe Carburettor; this pipe is made to fall lower than the vessel F and Kat I. By this arrangement heat-is not communicated from the carburettor to the intermittent feederl 'Io fill vessel AK with oil, it is simply necessary to unserew the vessel from chamber M. v .i

I clainias new, for carburetting gas Or air by heat at the burner, for obtaining light, forming the appaL ratu's with abe-ating aperture through its centre, also withheat regulator D, togethor'with the application of il-s l i arrn ement substantiall .as described. o ppy ng d g' y .JOSHUA Kinn.
